International Journal of Cerebrovascular Diseases 2016;24(6):524-528
Objective To investigate the correlation between thyroid antibody level and carotid atherosclerotic plaque in patients with acute ischemic stroke.Methods Consecutive patients with acute ischemic stroke were enrolled retrospectively.They were divided into a non-plaque group and a plaque group according to the findings of carotid artery color-Doppler ultrasonography.The plaque group was redivided into a stable plaque subgroup and a non-stable plaque subgroup.Chemiluminescence method was used to measure the serum thyroperoxidase antibodies (TPOAb) and thyroglobulin antibodies (TGAb) levels and they were compared.Results A total of 383 patients were enrolled in the study,including 116 (30.3%) did not have plaque and 267 (69.7%) had plaque,68 of them had unstable plaque,and 199 had stable plaque.The level of TGAb in the plaque group was significantly higher than that in the non-plaque group (Z =-4.826,P <0.001).Multivariate logistic regression analysis showed that the level of TGAb might be an independent risk factors for carotid plaque (odds ratio 1.007,95% confidence interval 1.001-1.012;P =0.016).The serum level of TPOAb in the stable plaque group was significantly higher than that in the unstable plaque group (Z =-2.114,P=0.035),but multivariate logistic regression analysis showed that it was not the independent risk factor for unstable plaque (odds ratio 1.001,95% confidence interval 0.996-1.006;P =0.786).Conclusions The level of serum thyroid antibodies increased in patients with acute ischemic stroke,especially the increased level of TGAb might be associated with the occurrence and development of carotid atherosclerotic plaque,however,it was not associated with the plaque stability.

Objective To investigate the drug induced liver injure(DILI)associated with Chinese herbal medicine and herbal related food supplements.Methods From 1982 to 2005.8.9 consecutive pa- tients were diagnosed as DILI based on their medication history,clinical manifestation,liver function and other laboratory tests.The final retrospection confirmatory diagnosis was made according to the interna- tional scoring system for DILI.Results The 82 DILI patients(28 men,54 females,age ranging from 16 to 81 years old)accounted for 2.2% of hospitalized patients with liver dysfunction.Among those patients with DILI,30.5% was caused by weight reducing drugs or food supplements,12.2% by drugs of derma tology,8.5% by drugs for cardiovascular disease,8.5% by drugs of rheumatology,7.3% by drugs of gynecology,6.1% by drugs for liver disease,6.1% by blood-lipids modulators,3.7% by drugs for thy- roid disease,3.7% by drugs for hyperplasia of mammary glands and 13.4 % by the others.The duration of medication was from 6 clays to 6 months and the incubation period was from 6 days to 3 months.DILI could be classified as acute hepatocellular injury(36.59%),acute cholestasis(39.02%)and mixtures (24.39%).About 10% patients were accompanied by allergic manifestations.All patients recovered rap- idly after stopping the relevant medicine.Conclusion Chinese herbal medicine and herbal related food supplements are a common cause of DILI in China.The awareness and monitoring improving DILI during herbs treatment is a critical issue in daily practice.
3. Research progress on application of epigenetics and metabolomics in traditional Chinese medicine
Chinese Traditional and Herbal Drugs 2020;51(19):4837-4845
Traditional Chinese medicine has multi-component, multi-target, and multi-path action characteristics and complexity, which makes the task of modernizing traditional Chinese medicine arduous, and many medical researchers have made unremitting efforts to this end. The development of systems biology and omics has ushered in an opportunity for the integration of traditional Chinese medicine and modern science. In particular, the characteristics integrity, dynamics, personalization, and interaction with the environment of epigenetics and metabolomics are consistent with function concept of traditional Chinese medicine. The application of popular DNA methylation, histone modifications, miRNA regulation of epigenetic research, and the application of metabolomics in the substance basis, quality control, pharmacodynamic action mechanism in traditional Chinese medicine research are reviewed in this paper. This paper also puts forward the idea that combining the two and innovative application can clarify the scientific connotation of the whole action mechanism of traditional Chinese medicine and the mechanism of multi-component, multi-channel, and multi-target synergistic action at the micro level, and explore a new research model for the scientific connotation of the core thought of traditional Chinese medicine.

Objective To investigate the protective mechanism of 7-nitro indazole (7-NI) in neonatal rats with hypoxic-ischemic brain damage. Methods Seventy-two Wistar rats of 7-day-old were randomly divided into the sham-operation、HIBD and 7-NI treated group. The HIBD models were established in 7-NI treated and HIBD groups.7-NI (100 mg/kg) or peanut oil (10 ml/kg) was injected intraperitoneally 0.5 h before hypoxia in 7-NI treated group or HIBD group. NOS,NO,SOD and MDA were examined at different time (1 h、2 h、6 h、8 h). Terminal deoxynucleotidyl transferase mediated dUTP-biotin nick end labeling(TUNEL) method was used to detect neuronal apoptosis. Results NOS and NO level of HIBD group at different time were significantly higher than that of the sham-operation group [NOS:1 h (3.345?0.367)U/mg, 8 h (4.469?0.275) U/mg vs (1.555?0.223) U/mg; NO: 1 h (2.419?0.254) ?mol/g, 8 h (3.556?0.309) ?mol/g vs (0.749?0.135) ?mol/g, P

Two regression models, based on panel data over the period of 2000-2011, are built and used to analyze what factors determine China's exports of primary and semi-finished products of traditional Chinese medicine to ASEAN. The results indicate that, China GDP, the ratio of ASEAN to China GDP per capita, average export price, the ratio of state-owned assets to total assets, have a significant positive influence on the export volumes of primary products of Chinese medicine. At the same time, RMB appreciation, the ratio of three kinds of foreign-invested assets to total assets, China-ASEAN Early Harvest Program, ASEAN-China Free Trade Area have a significant negative influence. In respect of the export volumes of semi-finished products of Chinese medicine, the significant influential factors are ASEAN GDP and the ratio of ASEAN to China GDP per capita. The former is positive and the latter is negative. In order to optimize the commodity composition of experts, it is needed to increase export volumes of both primary and semi-finished products of Chinese medicine. According to the analysis above, some proposals are put forward, such as, improving the performance of foreign capital, playing an exemplary and leading role in technological innovation by state-owned enterprises, taking advantage of bargaining power of suppliers, increasing outward foreign direct investment.
